As of Monday morning, the group "People United for Medical Marijuana" had submitted 523,168 valid signatures, according to the state Division of Elections website. The group needs to meet a Feb. 1 deadline for submitting 683,149 signatures.

The Florida Supreme Court on Dec. 17 approved the wording of the proposed constitutional amendment, which would legalize medical marijuana for a wide range of patients.

People United for Medical Marijuana, which also is known as "United for Care," has steadily moved toward meeting the signature requirement.

As an example, it had submitted about 400,000 signatures as of Dec. 17. If the group meets the requirement, the proposal would be on the November ballot. A similar proposal narrowly failed to pass during the November 2014 elections.
